Abstract (en)
[origin: US2017258558A1] A dental abutment coping or ring for securing a dental prosthesis to dental abutments. The coping or ring includes a body for insertion into a dental prosthesis, and a cavity or space sized to accept a head of the dental abutment. The interior surface of the cavity includes an interface region sized and shaped to accept the dental abutment in a retentive interface fit or a passive fit, depending on an angle of the interface surface. The exterior surface can have channels configured to contain a cement bonding the exterior surface to the dental prosthesis. A dental prosthesis system including the dental copings provides a retentive interference fit between the prosthesis and the dental abutments, even where the dental abutments are not parallel. A plurality of copings and abutments enables a retentive fit to varying degrees depending on the degree of interference fit in each coping and abutment.
